Title: Internal combustion engine exhaust system and silencer - uses tubes with multiple bores to cool exhaust gas
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/14
Filed: 1977-05-18
Abstract: A silencer forming part of the exhaust system of an internal combustion engine consists of two concentric tubes (51, 52).

Title: Double terminal clamp assembly for insulated wires - has two mirror-like asymmetric clamps coupled to form two sprung middle shanks
Inventor: HERDEGEN SIEGFRIED
IPC: H01R4/24

Title: Hollow fibre dialyser for artificial kidneys - with inlaid thicker thread forming splayed out bundle end
Inventor: HEILMANN KLAUS
IPC: A61M1/18
Filed: 1978-06-08
Abstract: A hollow-fibre dialayzer for use in artificial kidneys has the hollow fibres grouped to a mat and rolled up on a core. Parallel threads run across the hollow fibres and hold them together. One thread near the selvage of the mat is thicker than the others so that the fibre bundle end is expanded to a tulip shape when completely rolled up. This distributes the fibre ends better for the application of the casting compound. The ingress of the dialysate soln. is facilitated.

Title: Single phase async. motor speed control unit - uses speed indicator generator connected, for comparison of output signal with nominal value, in comparison circuit
Inventor: REYNA LANDECHO LUIS
IPC: H02P25/04
Filed: 1978-06-19
Abstract: The single-phase async. motors speed control comprising sawtooth voltage generator with output voltage controlling a Triac is designed to provide smooth control of motor speed without any abrupt changes in the motor speed, partic. when the drive voltage supply is temporarily disrupted and then stored. Thus, to this end, a speed-indicator generator is connected such that its output signal is compared with a nominal value in a speed (revs.) comparison circuit and is applied to a circuit for altering the slop of the voltage-speed characteristics of the speed-indicator generator. The output signal of the slope adjustment circuit is supplied to the control input of the sawtooth voltage generator, and a circuit for altering the acceleration characteristics is connected in parallel with the speed (revs.) comparison circuit. A control signal is used to control the circuit for altering the acceleration characteristics, the signal being derived from a store, for interruption or breakdown of the drive voltage supply in such a way that a gradual and controlled alteration of the async. motor speed results.

Abstract: The magnets consist esp. of the cpds. SECo5, or SE(Co, Mn, Fe, Cr) 17, where SE = are earths; and the initial powder is exposed to a magnetic field (I), and then converted into a coarse granulate which is magnetically neutral at its exterior.

Field (I) is pref. 15-30 kOe applied for a few microseconds, and is pref. followed by sieving the powder and then granulation on a pelletising plate; between rollers; or in a drum mixer. Field (II) is pref. max. 7.5 kOe, also applied as a pulse in the microsecond range. The initial powder is not free-flowing so it is difficult to fill pressing dies etc. The invention uses granulation to obtain a powder which is free-flowing.

Title: Prodn. process for optical transmission element - inserting, e.g. glass optical fibre, in spiral form torsion-free along tension-free sleeve and pressing together
Inventor: OESTREICH ULRICH DIPL ING
IPC: G02B6/44
Filed: 1978-07-31
Abstract: The prodn. process is for an optical transmission element, e.g. glass optical fibre, surrounded by a loosely fitting sleeve formed as a tension-free element. The transmission element runs torsion-free in spiral form along the length of the sleeve. The transmission element is coupled to the sleeve by a presser so they are compressed together.

The length of the indentation distancing can periodically vary.
Patent DE-2836760-A1 (DE)
Inventor: NEUMANN MANFRED ING GRAD
IPC: G08B26/00
Filed: 1978-08-23
Abstract: The alarm system, which can be used as a fire alarm, consists of a central station (2) which evaluates and, if appropriate, issues alarms, from which station (2) at least one two-wire sensor line (1), on which there are a plurality of sensors (19), is conducted. The sensors (19) are connected to one another in a sequential circuit in such a way that each sensor (19) connects the subsequent sensor (19) onto the sensor line (1) after a signal is issued. After the issuing of the signal of the last sensor (19) via a corresponding circuit in the central station (2), a brief interruption in the line voltage is brought about and, then, a new interrogation cycle is initiated. Thus, the interference influences and false alarms which occur with the conventional analog type of measurement value transmission and counting of the incoming reports are avoided to the greatest possible extent. <IMAGE>
